Subhrajit Makur 93b19a7e72 feat: add watch mode to gt status (#8) (#11) (#231) ...

* feat: add watch mode to gt status

- Add --watch/-w flag for continuous status refresh
- Add --interval/-n flag to set refresh interval (default 2s)
- Clears screen and shows timestamp on each refresh
- Graceful Ctrl+C handling to stop watch mode
- Works with existing --fast and --json flags

* fix(status): validate watch interval to prevent panic on zero/negative values

* fix(status): harden watch mode with signal cleanup, TTY detection, and tests

- Add defer signal.Stop() to prevent signal handler leak
- Reject --json + --watch combination (produces invalid output)
- Add TTY detection for ANSI escapes (safe when piped)
- Use style.Dim for header when in TTY mode
- Fix duplicate '(default 2)' in flag help
- Add tests for interval validation and flag conflicts
